Multiple geophysical and geodynamic studies demonstrate that intraplate volcanism occurs in continental and oceanic interiors away from plate boundaries, driven by mantle plumes, small-scale convection, or lithospheric interactions.
The retrieved papers consistently investigate instances of intraplate volcanism in both continental interiors (e.g., northeast China, Mongolia, Yellowstone) and oceanic settings (e.g., Rio Grande Rise), analyzing the sub-surface mantle dynamics that produce volcanic activity far from tectonic plate boundaries. There are no papers contradicting the definition or occurrence of intraplate volcanism.
